VARFABLE NOZZLE.

`iIPECI]5`I(.`.A'J.I ON forming part of Letters Patent No. 458,762, dated September 1, 1891.

Application filed May 29, 1891.

T0 all whom it may concern:

Be it known that I, ANSELME .ARRISTED CHARONNAT, a citizen o f the United States, residing at Nevada City, Nevada county, State of California, have inventcd an Improvement in Variable Nozzles; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the class of variable nozzles, and especially to those designed for the discharge of water.

My invention consists of a :nozzle having fitted to its end a transverse hollow seat, in which is adapted to be reciprocated a plate formed with a succession of apertures of varying diameters, said plate having'a stem on each end passing through stuffing-boxes, whereby it is moved to bring any of its aper' tures into alignment with the nozzle or to bring a solid portion opposite thereto to serve as a gate, as I shall hereinafter fully describe, and specifically point out in the claims.

The object of my invention is to provide a simple and effective nozzle the discharge of which can be varied and regulated by means of a regulating-plate so constructed and arranged as to be perfectlybalanced to permit the ready and easy operation.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure l is a horizontal section. Fig. 2 is a front view, the seat being broken away to show the regulatingplate. Fig. 3 is a crosssection of the regulating-plate on the line 7 7 of Fig. 1.

A is the nozzle. Across it is the seat B, in which is mounted and adapted to slide longitudinally the regulating-plate C. This plate is provided with a number of apertures c of different diameters, and it has extending from each end a stem D, connected therewith by a loose connection,in the manner of many valvestems, so that the plate may seat itself perfectly without interference from the stems. These Stems extend outwardly through each end of the seat B in stuffing-boxes Z), so that a tight joint is formed at each end. The regulating'plate is also provided With a longitudinal groove c', connecting its ends, and the ap` ertures o in said plate may be arranged or formed with a proper bevel to seijve as nozzles.

Serial No. 394,575. (No model.)

Either or both of the stuffing'boxes can be' removable to permit the removal of the regulating-plate.

In order to operate the regulating-plate any suitable mechanism may be employed. The simplest form of it is a lever E, controlled by a spring-pawl e, engaging a rackbar F, said' lever being connected by a link G with one of the stems of the regulating-plate.. The sizes of the nozzles may be'marked on the rack, so as to show which one is in use orto be used. `Another form is a shaft H, having on one end a bevel-pinion h, engaging With the beVel-pinion z' of a nut I, threaded upon the screw connecting-rod J of the plate-Stein. The shaft is operated by a hand-wheel K, and the amount of movement of the regulatingn plate maybe accurately determined by means of the indicator L, traveling over a graduated plate and operated by means of the beveled gearing Z with the shaft.

The operation of my device is as follows: When it is desired to change the capacity of the nozzle to a greater or less degree, the regulating-plate is moved to one side or the other in order to bring the proper aperture c into alignment with the nozzle=passage In this movement the plate operates With the exercise of but little power, as it is a balanced one, being mounted in its seat with astuffmg-x box at each end and a stem projecting from each end, whereby the water which passes to each end of the plate is confined and effects an equal pressure thereonA The groove c' in the plate is to permit of the ready passage of the Water to each end of the plate. The regu`` lating-plate serves also as a gate for the nozzle, when desired, by moving it into such a position that a solid portion between the apertures may be brought across the nozzlepassage, thereb y completely shutting off the Water.

` I-Iaving thus described my nvention, what I claim as new, and desire to secure by Letnr ters Patent, is-- i 1. Anozzle havinga transverse seat, aplate mounted in said seat and having apertures of various dial'neters adapted by the movement of the plate to be brought into alignment with the nozzle-passage, a stufiing-loox at each end of the seat, and a stem connected with each end of the plate and projecting outwardly through the stuffing-box, substantially as herein described.

2. A nozzle having a transverse seat and a longitudinally-movable plate inounted in said seat having apertures of different diameters adapted by the inoveinent of the plate to be brought into aligninent With the nozzle-passage, a groove extending longitudinally of the sliding plate, a stuffing-box at each end of the seat, and a stem at each end of the plate extending through the stuffing box, snbstantially as herein described.

8. A nozzle having the transverse seat With a stuffing-box in each end, the sliding plate mounted in the seat and having' apertures of different diaineters adapted to be brought into alignment With the passage of the nozzle, a stem connected with each end of the plate and extendin g outwardlythrough the stuffingbox, and suitable power con nections With one of said steins for moving the plate, substantially as herein described.

4. A nozzle having the transversc seat with a stuffing-box in each end, the sliding plate mounted in the seat and having apertures of different diameters adapted to be brought into alignment with the passage of the nozzle, a stem connected With each end of the plate and extendin g out'wardly through the stuffingbox, and suitable power connections With one of said stems for moving the plate, consisting of the shaft H, the connecting-i'od J, the nut on said rod, the pinions connecting the nut and shaft, and the indicator operated by the shaft H, substantially as herein described.

5. A nozzle having a transverse seat With end stuffing-boxes, and a longitudinally-sliding plate in said seat having end stems passing through the stuffingboXes, said plate crossing and regulating the nozzle-passage, substantially as herein described.

In witness Whereof I have hereunto set my hand.
